If you’re sewing your own clothes, curtains, or even doing regular mending (am I the only one constantly repairing the center seam on shorts?), it’s time to add a serger machine to your craft room. If you’re not familiar with sergers, they essentially replicate a commercial style stitch that uses 3 or 4 threads simultaneously instead of 2. The downside is that you need 4 of each color thread you plan to use to really be effective with it but the advantages far outweigh that inconvenience since everything you sew is going to be faster, stronger, and cleaner with a serger.
